    There are tools able to do so... nothing kernel-related.

    Yes, I had to do that a (very) few times, when the machine went south and
    logging was dead before. But is is not the "default way" by any long shot.

    It is no excuse to make _every_ kernel out there slow just for the
    hypothetical case it might crash sometime. Be optimistic, man! ;-)

    Who said it makes the kernel progress faster? Kernel progress' bottleneck
    is the few people who know it in and out, and so are in position to decide
    on the patches presented to them. (It also depends on the scarcity of
    kernel architects, and no thanks, a comittee doing that work would get me
    to run away from Linux _very_ fast indeed; but that is irrelevant here).

    Now, the productivity of the head developers/integrators is as high as the
    average quality of the patches they get. If Aunt Tillie and her sisters get
    a kernel debugger and start spewing off "Set to a random non-NULL value so
    it doesn't crash" patches kernel development will grind to a halt.

    Yes, debuggers have their uses. But the ones I've used on userland programs
    were much, much less useful than you seem to think. Sure, it is nice to be
    able to check on the values in a data structure to find out how it got
    screwed up, but that's it (and that is a very occasional use for me, when
    other approaches have failed). And a kernel Oops usually gives you enough
    to work that out.
